Finding my (electric) wheels

Long story but my main passion was scuba diving which is now out, at least for the time being. I'm looking to rekindle my love of cycling to regain the fitness lost after
a heart attack and subsequent mirtal valve replacement.
Riding unassisted isn't really possible at the moment, espc with these Welsh hills!!! I'm looking to convert my Nucleus 275 with a TSDZ2 motor so I still have to do a fair bit of work. Also looking to change the job to something part time and commutable by ebike.

Great forum full of interesting posts and advice for new ebikers like me. Keep up the good work
